Description

Technical Field

[0001] This utility model relates to the field of conductive paste application technology, and in particular to an automatic conductive paste application device. Background Technology

[0002] Conductive grease, also known as electrical composite grease, is a new type of electrical material that can be used on the contact surfaces of electrical connectors to significantly reduce resistance, prevent corrosion, and save energy. my country began researching and producing it in the 1980s, with dozens of varieties and models. These varieties share similar basic properties and are soft pastes made from mineral oil, synthetic grease, or silicone oil as base oils, with added special additives for conductivity, oxidation resistance, corrosion resistance, and arc suppression. The paste is produced through grinding, dispersion, modification, and refining.

[0003] Currently, the conductive paste used in overhead contact line laying is mostly applied manually. Workers apply the conductive paste to rubber gloves, and when the contact wire is laid in the laying frame via the laying trolley, the gloves are placed on the contact wire. As the contact wire slides over, the conductive paste is applied on top. This method of applying conductive paste alone cannot control the pressure, and the quality of the conductive paste application is inconsistent, with uneven thickness, which can easily cause poor return current in the power supply system and arcing of the pantograph. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic conductive paste application device. This device uses an atomized spraying method to conveniently and quickly apply conductive paste to the contact wire.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic conductive paste application device, comprising an air pump, a pressure module, a hydraulic module, a pressure plate, a hydraulic energy storage device, a spraying module, and a control module. The pressure module includes a control panel and two drive cylinders. A support plate is fixedly connected to the upper end of each drive cylinder. The control panel is fixedly connected to the support plate. The hydraulic module includes a hydraulic pump and a fixing rod. The hydraulic pump is fixedly connected to the upper end of the support plate, and the fixing rod is fixedly connected to the lower end of the support plate. The pressure plate is fixedly connected to the lower end of the fixing rod. A first valve and a second valve are fixedly connected to the pressure plate. The first valve is fixedly connected to the hydraulic module via an air pipe. The spraying module includes a mounting box and a pneumatic spray gun. The pneumatic spray gun is fixedly connected inside the mounting box. An adjustment knob is rotatably connected to the tail of the pneumatic spray gun, and a nozzle is fixedly connected to the head of the pneumatic spray gun.

[0006] Through the above technical solution, the device uses an air pump to introduce compressed air into the air pipe of the spraying module to atomize the conductive paste, and then uses a control module to control the gas flow rate to spray the conductive paste out in the form of atomized gas.

[0007] Furthermore, the hydraulic module also includes a pressurization delivery gauge and an air supply pressure indicator. The pressurization delivery gauge is fixedly connected to the front end of the hydraulic pump, and the air supply pressure indicator is fixedly connected to the rear end of the hydraulic pump.

[0008] Furthermore, a pressure gauge and a cylinder regulating valve are respectively provided on the front side of the control panel near the upper two sides. The cylinder regulating valve is rotatably connected to the surface of the control panel. An adjusting handle is rotatably connected to the front side of the control panel near the lower middle position. The control panel is fixedly connected to the first output port of the air pump through an air pipe.

[0009] Through the above technical solution, the pressure gauge can display the pressure of the cylinder inside the pressure module. After the air pump is turned on, the pressure module is charged. This pressure is used to supply energy for the overall lifting and lowering of the transmission device. The cylinder regulating valve can be rotated to adjust the pressure of the drive cylinder. The working pressure of the pressure module is about 0.3-0.4 MPa. The pressure determines the speed of the device's lifting and lowering. The adjusting handle can control the movement of the device. When the handle is in the "stop" position, the drive cylinder stops expelling air, and the overall support cannot move up or down. When it is in the "rise" or "fall" position, the drive cylinder expells air to supply energy to the transmission device behind the control panel, and the entire device moves up and down.

[0010] Furthermore, a track is slidably sleeved at the rear end of the control panel, one end of the track is fixedly connected to the support plate, and the other end of the track passes through the support plate and is fixedly connected to the outer wall of the cylinder body of one of the drive cylinders.

[0011] Through the above technical solution, the device can rise and fall within the allowable range of track movement, preventing excessive upward or downward pressure from damaging the support structure. At the same time, when in the "stop" position, it can play a fixing role to prevent the device from losing pressure and dropping.

[0012] Furthermore, the input end of the hydraulic energy storage device is fixedly connected to the output end of the pressure delivery meter via an air pipe, and the output end of the hydraulic energy storage device is fixedly connected to the input end of the pneumatic spray gun via an air pipe.

[0013] The above technical solution addresses the issue of unstable air pressure provided by the air pump after passing through the device, as well as errors in the hydraulic pump pressure, resulting in uneven application speed when the conductive paste is output. The hydraulic energy storage device can store excess hydraulic energy, and when the output hydraulic pressure is too low, the hydraulic energy storage device will release the stored energy to stabilize the output hydraulic pressure of the conductive paste.

[0014] Furthermore, the control module is electrically connected to a power supply module via wires, and the control module is fixedly connected to the second output port of the air pump via an air pipe.

[0015] Through the above technical solution, the control module is powered separately by the power module. The second output port of the air pump is connected to the control module, and then converges with the pressure module to output conductive grease. The up and down adjustment buttons on the control module can control the gas output speed to a specific level. At the same time, the power display on the control module can display the output level. This control module is made of a grease metering spray valve controller.

[0016] Furthermore, the lower ends of both drive cylinders are fixedly connected to mounting bases, and the upper end of the mounting bases is provided with a material cylinder, with the pressure plate movably sleeved inside the material cylinder.

[0017] With the above technical solution, the material cylinder contains conductive paste raw material. As the pressure plate descends, valve two is closed and valve one is opened at the same time. The air pressure will push the conductive paste to the hydraulic module.

[0018] This utility model has the following beneficial effects:

[0019] Compared with existing technologies, this automatic conductive paste application device, through the coordinated operation of an air pump, pressure module, hydraulic module, pressure plate, valve one, valve two, hydraulic energy storage device, spraying module, and control module, can atomize the conductive paste by introducing compressed air into the air pipe of the spraying module before applying the conductive paste. Then, the control module controls the gas flow rate to spray the conductive paste out in the form of atomized gas. Compared with manual application, the spraying quality is higher, the thickness is more uniform, and the spraying efficiency is higher. Attached Figure Description

[0028] Reference Figure 1-4This utility model provides an automatic conductive paste application device, comprising an air pump 1, a pressure module 2, a hydraulic module 3, a pressure plate 4, a hydraulic energy storage device 7, a spraying module 8, and a control module 9. The air pump 1 provides power to the spraying and pressure module 2. After receiving air pressure, the pressure module 2 converts the air pressure into power, which can control the lifting and lowering movement of the entire device. The pressure module 2 includes a control panel 201 and two drive cylinders 206. The back of the control panel 201 is connected to the hydraulic module 3 via an air pipe, providing power to the hydraulic module 3. The hydraulic module 3 is mainly used to handle the pressure state of the conductive paste. The upper ends of the two drive cylinders 206 are fixed. A support plate is fixedly connected to the control panel 201. The hydraulic module 3 includes a hydraulic pump 301, a pressure delivery gauge 302, an air supply pressure indicator 303, and a fixing rod 304. The hydraulic pump 301 is fixedly connected to the upper end of the support plate. After the conductive paste is transported to the hydraulic pump 301, the hydraulic pump 301 converts air pressure into hydraulic pressure, allowing the conductive paste to have pressure and flow. Simultaneously, in conjunction with the air supply pressure indicator 303, air can only be supplied to the hydraulic pump 301 when the pressure is greater than 0.4 MPa; otherwise, the lower valve will open to release the gas. The adjustment knob in the middle of the pressure delivery gauge 302 in front of the hydraulic pump 301 can adjust the amount of hydraulic pressure supplied by the hydraulic pump 301. Generally, it maintains... The pressure plate is held at 5-6 MPa. A fixed rod 304 is fixedly connected to the lower end of the support plate, and a pressure plate 4 is fixedly connected to the lower end of the fixed rod 304. The overall control of the pressure plate 4 is controlled by the pressure module 2. The support plate is raised or lowered by the drive cylinder 206, which in turn raises or lowers the fixed rod 304, and consequently the pressure plate 4. A pressure gauge 302 is fixedly connected to the front end of the hydraulic pump 301, and an air supply pressure indicator 303 is fixedly connected to the rear end of the hydraulic pump 301. Valves 5 and 6 are fixedly connected to the pressure plate 4. When valve 5 is opened, the air pressure pushes the conductive paste to the hydraulic module 3. Valve 6 acts as a regulator. After the pressure plate 4 is placed into the material cylinder 11, the valves are opened... Door 26, close valve 15, adjust the pressure module 2 to the "down" position via the adjustment handle 204, the pressure plate 4 moves down until the conductive paste just overflows from valve 26, indicating that the pressure plate 4 is just in contact with the conductive paste, then turn the position to "stop", valve 26 closes and valve 15 opens, ensuring that the conductive paste is smoothly delivered from valve 15. Valve 15 is fixedly connected to the hydraulic module 3 via an air pipe. The spraying module 8 includes a mounting box 801 and a pneumatic spray gun 802. The pneumatic spray gun 802 is fixedly connected in the mounting box 801. The tail of the pneumatic spray gun 802 is rotatably connected to an adjustment knob 803, and the head of the pneumatic spray gun 802 is fixedly connected to a nozzle 804.

[0029] Through the above technical solution, the device uses an air pump 1 to introduce compressed air into the air pipe of the spraying module 8 to atomize the conductive paste, and then uses a control module 9 to control the gas flow rate to spray the conductive paste out in the form of atomized gas.

[0030] Pressure gauges 202 and cylinder regulating valves 203 are respectively installed on the upper sides of the front face of the control panel 201. The cylinder regulating valves 203 are rotatably connected to the surface of the control panel 201. An adjusting handle 204 is rotatably connected to the lower middle position of the front face of the control panel 201. The control panel 201 is fixedly connected to the first output port of the air pump 1 through an air pipe. The pressure gauges 202 can display the pressure of the cylinder inside the pressure module 2. After the air pump 1 is turned on, the pressure module 2 is charged. This pressure is used to supply the energy for the overall lifting and lowering of the transmission device. The throttle valve 203 can be rotated to adjust the pressure of the drive cylinder 206. The working pressure of the pressure module 2 is approximately 0.3-0.4 MPa. The pressure determines the speed of the device's ascent and descent. The adjustment handle 204 can control the movement of the device. When the handle is in the "stop" position, the drive cylinder 206 stops expelling air, and the overall support cannot move up or down. When in the "rise" or "fall" position, the drive cylinder 206 expells air to power the transmission device behind the control panel 201, and the entire device moves up and down. The transmission device is the track 205.

[0031] The rear end of the control panel 201 is slidably fitted with a track 205. One end of the track 205 is fixedly connected to the support plate, and the other end of the track 205 passes through the support plate and is fixedly connected to the outer wall of the cylinder of one of the drive cylinders 206. The device can rise and fall within the allowable range of movement of the track 205 to prevent excessive upward or downward pressure from damaging the support structure. At the same time, when it is in the "stop" position, it can play a fixing role to prevent the device from losing pressure and dropping.

[0032] The input end of the hydraulic energy storage device 7 is fixedly connected to the output end of the pressure delivery gauge 302 via an air pipe, and the output end of the hydraulic energy storage device 7 is fixedly connected to the input end of the pneumatic spray gun 802 via an air pipe. Since the air pressure provided by the air pump 1 after passing through the device is unstable, the pressure of the hydraulic pump 301 has an error, resulting in uneven application speed when the conductive paste is output. The hydraulic energy storage device 7 can store excess hydraulic energy. When the output hydraulic pressure is too low, the hydraulic energy storage device 7 releases the stored energy to stabilize the output hydraulic pressure of the conductive paste.

[0033] The control module 9 is electrically connected to the power module 10 via wires. The control module 9 is fixedly connected to the second output port of the air pump 1 via an air pipe. The control module 9 is powered independently by the power module 10. The second output port of the air pump 1 is connected to the control module 9, and then converges with the pressure module 2 to output conductive paste. The up and down adjustment buttons on the control module 9 can control the gas output speed to a specific level. At the same time, the power display on the control module 9 can display the output level. The control module 9 is made of a grease metering spray valve controller. The output end of the control module 9 is connected to the spraying module 8. The air is output at a constant speed, carrying the conductive paste out of the spraying module 8. The spray nozzle 804 is located in the grooves on both sides of the contact line. When the pneumatic spray gun 802 is working, it can spray the conductive paste into the grooves.

[0034] Both drive cylinders 206 have mounting bases fixedly connected to their lower ends. A material cylinder 11 is provided on the upper end of the mounting base. The pressure plate 4 is movably sleeved inside the material cylinder 11. The material cylinder 11 contains conductive paste raw material. After the pressure plate 4 descends, the valve 2 6 is closed and the valve 1 5 is opened, the air pressure will push the conductive paste to the hydraulic module.
